Rear 11.5" Brake Rotor - Speed Holes

Rear 11.5" Brake Rotor - Speed Holes

Classic Speed Hole Brake Disc is a DOT-approved, OE-style rear brake rotor built for dependable stopping power and long service life. Made from low-carbon 420 stainless steel and precision ground for maximum flatness, it delivers consistent braking performance while resisting warping and corrosion. The drilled “speed hole” design reduces weight, sheds water, and helps dissipate heat—keeping things cool and predictable when it matters most.

Bolt hole size: 3/8"

Come with an aluminum adapter to work with both a 2" or 2.220" hub flange

Finished in satin stainless
